It belongs to the 3000 series, powered by 7th Gen Intel Core processors. It is often confused with Latitude 3480, but they use different batteries. Its built-in lithium-ion battery is the most frequently replaced part after years of charge cycles. This guide includes&nbsp; specs, hands-on runtime test, installation notes and complete FAQ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dell supplied two factory battery options for Latitude 3488:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-3488-replacement-battery.html\"><strong>WDX0R<\/strong><\/a> <strong>(WDXOR, 42Wh, 3-cell, 11.4V Li-ion)<\/strong>\uff1aCross PN: 3CRH3, T2JX4, FC92N, CYMGM, FW8KR. This is the standard original battery for most 3488 units.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-3488-replacement-battery.html\"><strong>33YDH<\/strong><\/a> <strong>(56Wh, 4-cell, 15.2V Li-ion)<\/strong>\uff1aCross PN: PVHT1, 99NF2, 81PF3. This is the optional high-capacity upgrade battery for the same chassis.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Important reminder: Latitude 3488 can take both WDX0R and 33YDH, but <strong>3480 and 3488 are not the same model<\/strong>. Many sellers mix them up in listings. Always verify the part number printed on your old battery label.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hands-on Product Review<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We tested certified <a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-3488-replacement-battery.html\">replacement WDX0R 42Wh and 33YDH 56Wh batteries<\/a> on a Latitude 3488 configured with i5-7200U, 8GB DDR4 RAM, 256GB SSD, HD non-touch screen, Windows 10 Pro.

No random percentage drops or \u201cbattery not recognised\u201d alerts.<\/li>\n\n\n\n<li>ExpressCharge works reliably: With a genuine Dell 65W barrel charger, a healthy battery can reach 80% charge within roughly 60 minutes.<\/li>\n\n\n\n<li>Stable discharge curve: No sudden hard shutdown at 10\u201320% remaining charge, a common flaw of cheap generic batteries without qualified BMS protection.<\/li>\n\n\n\n<li>Exact OEM shape, mounting holes and connector: Direct drop-in fit after removing the bottom base cover, no cutting or modification required.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Weaknesses &amp; Important Caveats<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Only two\u00a0 factory options: <a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3488-battery.html\">42Wh WDX0R<\/a> and 56Wh 33YDH. No higher-capacity factory battery beyond 56Wh for this chassis.<\/li>\n\n\n\n<li>Compatibility warning: WDX0R also fits Inspiron 5368, 5378, 5568, 5578; 33YDH also fits Latitude 3380, 3480, 3580, 3490, 3590. But <a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3488-battery.html\">WDX0R<\/a> and 33YDH have different voltage and connector, do not order randomly. Always match the PN from your old battery.<\/li>\n\n\n\n<li>Rated cycle life is approximately 300 full charge cycles under normal room temperature. After that, usable capacity will gradually decline.<\/li>\n\n\n\n<li>Installation requires removing the bottom base cover. Before touching internal parts, power off the laptop, unplug the barrel charger, disconnect the battery cable and press the power button for 10 seconds to release residual static power. Never bend, twist or puncture the lithium-ion cell.<\/li>\n\n\n\n<li>Swollen batteries are hazardous. Stop using the laptop immediately if you spot bulging, warped bottom cover or lifted trackpad. Do not squeeze, pierce or attempt to charge a swollen battery. Deliver it to a professional lithium battery recycling station.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Battery Maintenance Tips<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use the original Dell 65W 7.4mm barrel AC adapter. Higher-wattage Dell barrel adapters work, but low-quality unbranded adapters may trigger slow charging or charging failures.<\/li>\n\n\n\n<li>Avoid draining the battery down to 0% frequently. Deep discharge damages the protection board and shortens service life.<\/li>\n\n\n\n<li>If you keep the laptop docked and plugged in all day, use Dell Power Manager to set a charge limit at 60\u201380% to slow battery aging.<\/li>\n\n\n\n<li>Run battery diagnostics in SupportAssist or use powercfg \/batteryreport in Windows Command Prompt to track capacity degradation.<\/li>\n\n\n\n<li>Keep the laptop away from high heat, direct sunlight or soft cushions while charging; heat is the top cause of lithium-ion battery degradation.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>FAQ for<\/strong> <a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3488-battery.html\"><strong>Replacement Dell Latitude 14 3488 Battery<\/strong><\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q1: Which battery part numbers fit Latitude 3488?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Two compatible options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>WDX0R (WDXOR, 42Wh, 3-cell, 11.4V Li-ion), cross PN: 3CRH3, T2JX4, FC92N, CYMGM, FW8KR<\/li>\n\n\n\n<li>33YDH (56Wh, 4-cell, 15.2V Li-ion), cross PN: PVHT1, 99NF2, 81PF3 Both fit Latitude 3488, but they are not interchangeable with each other. Check your old battery PN before ordering.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q2: Can I upgrade from WDX0R 42Wh to 33YDH 56Wh for longer runtime?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Yes, the Latitude 3488 chassis supports both versions. You can upgrade to 33YDH 56Wh to get significantly longer battery life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q3: My Latitude 3488 only runs when plugged in, Windows shows 100% battery. Is the battery dead?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: This is a typical failure symptom. First run Dell SupportAssist battery diagnostics and check battery data in BIOS. If the diagnostic marks the battery failed, replacement is needed. Rarely, this issue can also be caused by a loose battery connector or faulty charging circuit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q4: Can I replace the battery myself?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: It is internal and non-hot-swappable. You need to remove the base cover, disconnect the battery cable and remove fixing screws. If you lack electronics repair experience, hire a professional technician. Always power off and unplug the charger before disassembly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q5: Do WDX0R and 33YDH support ExpressCharge?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Original OEM WDX0R and 33YDH support ExpressCharge. Only certified replacement batteries with the correct smart communication chip support fast charging. Cheap generic batteries usually skip this function and charge slowly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q6: How do I check my battery health?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Two reliable ways:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Press F2 during boot to enter BIOS and open the Battery Information page.<\/li>\n\n\n\n<li>Open Command Prompt and run powercfg \/batteryreport, or launch SupportAssist to run the battery hardware scan.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q7: What charger should I use for Latitude 3488?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Dell original 65W 7.4mm barrel AC adapter is recommended. USB\u2011C PD chargers are not native for this model and may not charge reliably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q8: How many cycles can I expect from a new replacement battery?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Around 300 full charge cycles under normal office temperature. With light daily use and proper care, it can stay usable for roughly 2\u20133 years before capacity drops noticeably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q9: Is it safe to leave the laptop plugged in 24\/7?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Dell firmware stops charging once full. However, keeping the battery at 100% under warm conditions accelerates aging. If the laptop stays docked long-term, set a charge limit via Dell Power Manager whenever possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q10: What should I do if my battery is swollen?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Stop using the laptop right away. Disconnect the power adapter. Do not squeeze, puncture or force the battery out. Take it to a repair shop or authorised e-waste recycling centre for safe disposal.More info:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-3488-replacement-battery.html\">https:\/\/www.pc-battery.co.uk\/dell-latitude-3488-replacement-battery.html<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3488-battery.html\">https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3488-battery.html<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dell Latitude 14 3488 Battery Replacement Dell Latitude 14 3488 Battery Review &amp; Buyer Guide The Dell Latitude 14 3488 (Reg model P79G) is a 14-inch business laptop for office, education and mobile work.
